[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] See attached Figure 1-2 , an automatic feeding device for feed comprises a bottom plate 1, a box body 2 is fixedly connected to the top surface of the bottom plate 1, the bottom surface and one side surface of the box body 2 are transparent, a support 3 is fixedly connected to the position corresponding to the top edge of the bottom plate 1 and the transparent side of the box body 2, an elastic plate 4 is fixedly connected to the top of the support 3, one end of the elastic plate 4 away from the support 3 horizontally extends into the inner cavity of the box body 2 and is transmission-connected to a pry bar assembly fixedly installed on the top surface of the box body 2, a rope 9 is fixedly connected to one end of the pry bar assembly away from the elastic plate 4; one end of the rope 9 away from the pry bar assembly downwardly penetrates the top surface of the box body 2 and is fixedly connected to a magnet 10; an outer cylinder 11 and an inner cylinder 12 are vertically fixedly connected to the top surface of the inner cavity of the box 2, and the inner cylinder 12 is limited to The outer cylinder 11 is inside and the axes of the two coincide with each other, a baffle 13 is fixedly connected to the bottom end surface of the outer cylinder 11, and the bottom end of the inner cylinder 12 passes through the baffle 13 downward; the magnet 10 is confined in the inner cylinder 12; a plurality of through grooves 14 are opened on the side wall of the inner cylinder 12 above the baffle 13, and an upper limit block 15 and a lower limit block 16 are fixedly connected to the inner cavity side wall of the inner cylinder 12 above and below the through grooves 14, respectively; an iron cylinder 17 is slidably provided at a position between the upper limit block 15 and the lower limit block 16 in the inner cylinder 12, and the magnet 10 can be adsorbed on the top surface of the iron cylinder 17; a feed pipe 18 is passed through the top surface of the box body 2 at a position corresponding to the outer cylinder 11.

[0022] The elastic plate 4 can be bent by pressure, and will return to a horizontal state after the pressure is lost. Therefore, when the pet walks onto the elastic plate 4, the elastic plate 4 will be bent, and will return to its original state after leaving. When the elastic plate 4 is bent, the magnet 10 will be driven to move upward through the pry bar assembly and the rope 9. A through hole is provided on the top surface of the box body 2 at a position corresponding to the rope 9, so that the rope 9 can pass through the top surface of the box body 2 normally. The axis of the through hole coincides with the axis of the inner cylinder 12 but the diameter is smaller than the diameter of the inner cylinder 12. The inner cylinder 12 and the outer cylinder 11 are both vertically fixed to the top surface of the inner cavity of the box body 2. The area outside the inner cylinder 12 and inside the outer cylinder 11 is used to hold pet food. The feeding pipe 18 also corresponds to the area between the outside of the inner cylinder 12 and the inside of the outer cylinder 11, and is used to pour pet food.

[0023] The bottom end of the through groove 14 is flush with the top surface of the baffle 13, and the feed can flow smoothly from the through groove 14 into the inner tube 12; the iron cylinder 17 is a hollow structure, which can reduce the mass. The diameter of the iron cylinder 17 is slightly smaller than the inner diameter of the inner tube 12, and it can slide downward in the inner tube 12 and can only slide between the upper limit block 15 and the lower limit block 16. The height of the iron cylinder 17 is greater than the height of the through groove 14; the position of the lower limit block 16 needs to ensure that when the iron cylinder 17 abuts against it, the iron cylinder 17 can completely cover the through groove 14; the position of the upper limit block 15 needs to ensure that when the iron cylinder 17 abuts against it, the through groove 14 will be completely exposed; this setting can control the outflow of pet food; in addition, the pry bar assembly needs to ensure that the lowest point of the movement stroke of the magnet 10 can be adsorbed together with the top surface of the iron cylinder 17 at the lowest position (the position where the iron cylinder 17 abuts against the lower limit block 16), and the highest point of the movement stroke of the magnet 10 is higher than the upper limit block 15; the outer tube 11 is made of transparent glass, which is convenient for observing the amount of feed inside.

[0024] Working principle: When the pet walks onto the elastic plate 4, the elastic plate 4 is bent, which drives the magnet 10 to move upward, and the magnet 10 drives the iron cylinder 17 to move upward. At this time, the through groove 14 will be exposed, and the pet food between the inner cylinder 12 and the outer cylinder 11 will flow into the inner cylinder 12 through the through groove 14, and then flow down from the bottom of the inner cylinder 12 and fall onto the elastic plate 4, so that the pet can eat the food. In the process of the iron cylinder 17 continuing to rise driven by the magnet 10, the iron cylinder 1 7 will be blocked by the upper limit block 15, the magnet 10 continues to rise, the iron cylinder 17 will separate from the magnet 10, the iron cylinder 17 will fall, and finally fall on the lower limit block 16 and block the through slot 14 again, and no more feed will fall down. The size of the through slot 14 needs to ensure that a sufficient amount of feed can flow out each time through the above process. After the pet eats the outflowing feed, it leaves the elastic plate 4, the elastic plate 4 returns to the horizontal level, the magnet 10 falls, and is adsorbed together with the iron cylinder 17 again, waiting for the next action.

[0025] A further optimized solution is that the sled rod assembly includes a support plate 6 fixedly connected to the top surface of the box body 2, a rotating rod 7 is rotatably installed on the side of the support plate 6, one end of the rotating rod 7 is hinged with a connecting rod 5, the end of the connecting rod 5 away from the rotating rod 7 passes through the top surface of the box body 2 from top to bottom and is hinged with the top surface of the elastic plate 4; the end of the rotating rod 7 away from the connecting rod 5 extends to the top of the inner tube 12 and is fixedly connected with a lifting ring 8; the rope 9 is fixedly connected to the lifting ring 8.

[0026] The connecting rod 5 is hinged to the top surface of the end of the elastic plate 4 away from the support 3, and a hole is also opened at the top surface of the box body 2 at the position corresponding to the connecting rod 5. The diameter of the hole needs to ensure that the connecting rod 5 can operate normally without being affected; when the pet walks to the top surface of the elastic plate 4, the elastic plate 4 is bent, and the end of the elastic plate 4 away from the support 3 moves downward, thereby pulling the connecting rod 5 downward. In this way, the end of the rotating rod 7 hinged to the connecting rod 5 moves downward, and the end fixed to the ring 8 rises, thereby pulling the magnet 10 up through the rope 9; similarly, when the pet leaves the elastic plate 4, the end of the elastic plate 4 away from the support 3 rises, the connecting rod 5 rises, the end of the rotating rod 7 hinged to the connecting rod 5 rises, and the end fixed to the ring 8 moves downward, thereby driving the magnet 10 to descend.

[0027] According to a further optimized solution, a rice bowl 19 is fixedly connected to the top surface of the elastic plate 4 just below the inner cylinder 12 .

[0028] The food bowl 19 is used to receive the feed dropped from the inner cylinder 12 to prevent the feed from being scattered on the elastic plate 4, making it convenient for the pet to eat.

[0029] According to a further optimized solution, the bottom surface of one end of the elastic plate 4 away from the support 3 is fixedly connected to the bottom plate 1 through a spring 20 .

[0030] The spring 20 can assist the elastic plate 4 to return to a horizontal state, and the elastic force of the spring 20 cannot affect the pet's ability to bend the elastic plate 4 normally.

[0031] According to a further optimized solution, the baffle 13 is in the shape of an inverted truncated cone.

[0032] The inverted truncated cone-shaped baffle 13 allows the feed in the outer cylinder 11 to pass through the through slot 14 smoothly without being blocked at the bottom end of the outer cylinder 11 .

[0033] According to a further optimized solution, the side of the rice bowl 19 away from the support 3 is higher than the side close to the support 3 .

[0034] The side of the rice bowl 19 away from the support 3 is higher than the side close to the support 3, which can effectively prevent the feed from bouncing into a more inner position when it falls.
